Application led November 20, 1916. Serial No. 132,317.

the spout incommunication with vthe air chamber.

The primary object of the invention 1s to provide a Ventilating spout ofthis nature which shall be of extremely simple construction, cheap tomanufacture and very eiiicient.

Another object of the inventlon 1s to provide a Ventilating spout whichby slight,

Amodification may be constructed to be received entirely within a canand form what might be termed an interior spout.

With these and other objects-in view the invention consists of certainfeatures of construction, combination and arrangement of parts as willbe hereinafter fully described, illustrated and claimed.

Figure 1 is a fragmentary sectional view of a can showing our improvedspout applied thereto.

Fig. 2 is a horizontal sectional view on the plane of line 2 2, of Fig.1.

Fig. 3 is a top plan view of a can showing a modified form of spoutapplied thereto.

Fig. 4: is a top plan view of the modified spout.

Fig. 5 is a vertical sectional view of the modified spout and a portionof a can; and

Fig. 6 is a section on the plane of line 6, 6, of Fig. 5.

l Referring-in detail to the drawing by numerals, 1 designates as anentirety a can to which our improved Ventilating spout is applied. Inthe embodiment shown in Figs. 1 and 2, the spout is formed with an innercylindrical shell 2, an outer cylindrical shell 3 spaced' from the shell2 and providing an air chamber 4.-. rPhe shell 3 extends outwardlybeyond the shell 2 and is externally threaded for engagement with a cap5. The tcp wall 6 of this can is apertured to receive the spoutand isformed with a bead 7 around theaperture which acts asa reinforcement andwhich closely engages the shell 3 of the spout.

The shells 2 and 3 terminate at their inner ends in an inclined planeand they project a slight distance into the can. A wal-l 8 connects theinner ends of the shells 2 and 3 forming a closure for the innerterminal of the air chamber 4. A vent ipe 9 extends through the shell 3and terminates in communication with the air chamber. This pipe extendsfrom the spoutto a point adjacent the upper end of the can so that whenthe can is tipped to permit the contents thereof to iow through thespoilt, air will flow into the can and prevent a vacuum forming therein.Y

In Figs. 3 to 6 inclusive, we have showna somewhat modified form ofspout embodying the same principle as set forth with reference to thespout illustrated in Fig. 1. In the modified construction the spout andvent tube are formed integrally and are positioned entirely within thecan.

Referring t0 this construction by numerals, 10 designates a can having atop wall 11, whichv is formed with an opening 12. The spout 13 has aninner frusto-conical passage formed by the shell 141, land around thisshell is an air chamber 15 having the side wall 16 and end 0r bottomwall 17.

-Extending from the air chamber is a vent tube or air passage 18, bestshown in Fig. 4. When the spout is secured to the top of a can said topwill form a top wall for the vent tube 18 and an air chamber 15. Theshell 14 extends outwardly in a plane iush with the outer face of thecan top and is spaced from the' edge of the opening 12 to allowatmospheric communication to the air chamber 15. To close the spout andprevent loss of liquid when 'the can is being shipped, we provide a seal19 which is Soldered or otherwisesecured to the top of the can so as toclose the spout.

From the foregoing description taken in connection with the accompanyingdrawing,

exact terms required by law, and knowing that it comprises novel, usefuland Valuable improvements in the art to Which it per tains, We herestate that We do not Wish to be limited to the precise construction andarrangement of the several parts, as herein set fort as the same may bevariously modified by a skilled mechanic Without departing from thespirit of the invention.

lfvlhat we claim and desire to secure bylietters Patent of the UnitedStates, is the following, to Witz- Claims.

1. A can having a Wall formed with an opening therein, a Ventilatingspout Within said can consisting of an air passage having at one endthereof an annular air chamber' and a central liquid passage project-ingoutwardly in said opening and terminating in a plane i'lush with theouter face of the Wall of said can, said annular air chamber com'-municating with said opening and a detachable seal secured to said canadapted to cover said annular air chamber and said central liquidpassage.

2. In combination, a can having a top wall formed with an opening, aVentilating spout Within said can in alinement with said Leeeie opening,the spout being formed With a central frusto-conical shell terminatingWithin said opening and spaced from the sides thereof, said shellforming a central liquid passage, an outer shell encircling said innershell and forming an air chamber,

and a vent pipe formed integrally With said outer shell andcommunicating with the air chamlber.

3. A can provided with an opening, ventilating means and liquid passageconnected with said opening, said Ventilating means consisting of an airpassage having at one end an annular` air chamber, and said liquidpassage being formed centrally Within said air chamber and projectingthrough said opening in the can, and means to close said air chamber andthe liquid passage flush with ythe outer face Wall of the can.

ln testimony that We claim the foregoing we have hereto set our hands inthe presence of two witnesses, this 31st day of Oct. 1916.
